The bar graph LEDs light when foam concentrate is being injected,
indicating the approximate capacity of the foam concentrate system that
is being used. The ARROW buttons control the foam concentrate injection
rate.
Optional Dual Tank System
(See Figure 3-3: “Dual Tank Selectors.”)
An optional dual tank
system, air or manually
operated, allows the
operator to select the
foam concentrate
source.
During most CAFS oper-
ations, Class “A” foam
concentrate is used from
one of the foam tanks.
The dual tank system
selector is in the TANK A
position.
Use of Class “B” foam
concentrate requires
placing the dual tank
selector in the TANK B position.
Each dual tank selector, air or manual, has a FLUSH position to flush the
Hale FoamLogix foam pump after use and prevent mixing of incompatible
foam concentrates. Control switches on the MDT II and ADT signal the
Hale FoamLogix system whether the selector is in TANK A, TANK B or
FLUSH position. The control then selects the preset percentage (%) for
the foam tank being used.
